[Class 44] A spring-controlled pivoted door handle, for both right- and lefthand doors, comprises an attachment piece, which has at its inner side a stop or stops and in which is rotatably supported one end of the handle; this end of the handle has coiled round it a spring, the ends of which abut the stop or stops, and a member is secured to the inner end of the handle to co-operate with either end of the spring. An attachment plate a, Fig. 2, is formed with a hollow boss, having a hole in its front for a trunnion-like part d on the inner end of the handle e, and having at its inner side two diametrically opposite stops g ; a spring h surrounds the trunnion-like part d, its ends being bent to abut against and project beyond the stops g ; on the inner end of the part d is secured a retaining piece i, which contacts the inner face of the attachment plate a, and has in its edge two segmental notches providing an intermediate projection m and two shoulders k against which the extended ends of the spring abut. When the handle is moved, one of the shoulders k carries one end of the spring with it ; movement of the handle is limited by the contact of one side of the projection m with the other end of the spring. This end being held by its stop g. On release, the handle is returned to its normal position by the spring h. In a modification, a single stop is provided on the attachment plate ; the ends of the spring bear against its opposite sides, and the intermediate projection on the retaining piece lies between the ends of the spring. Alternatively, Fig. 8, the boss b consists of a ring formed on the attachment plate a and having in it a gap n, the ends of which limit movement of the handle and through which the ends of the spring h extend ; outside the gap n is a stop o for the ends of the spring between which lies a projection p bent inwards at right angles on the retaining piece i. In another modification, Fig. 11, the attachment plate a and spring h are as shown in Fig. 2, but secured to the part d of the handle is a collar r with a radial projection s which carries with it one end of the spring when the handle is moved. The retaining piece i has a projection t which engages a stop u on the attachment plate to limit movement of the handle. This construction is directly applicable to either a right- or a left-hand door since the handle can be moved to either of two operative positions 180 degrees apart in which the projection s on the collar r bears on different ends of the spring h. For use on a cupboard door or the like, any one of the handles described above is provided with an extension to be engaged by a hasp on the door frame. Specification 577,878 is referred to.

IPC: F16D41/16
Filed: 1951-09-17
Abstract: 701,279. Freewheel clutches. HILL, T. A., and BARFORD (AGRICULTURAL), Ltd. Feb. 28, 1952 [Sept. 17, 1951], No. 21763/51. Class 80 (2) A free-wheel device, particularly for coupling coaxial driving wheels of a vehicle to a common axle so as to allow either wheel to over-run the other when turning a corner, comprises an outer internally-toothed ring 4, a coaxial inner pawl carrying member 2, and pawls 7, pivoted at 8 in the pawl-carrying member in one of two positions, in which the pawls extend towards the teeth of the ring 4 in either of two directions, oppositely inclined to radii drawn from the common axis of the members 2, 4 through the pawl pivots, whereby the pawls transmit rotation in either of two directions according to which of the two positions they are assembled in, the teeth being of symmetrical V-shape and the pawls having square ends. As shown, the inner member 2 is secured to the driving axle 1, of a vehicle by a clamping screw 3, and the outer member 4, which is provided with a greaser 6, carries the driving wheel, the inner member being adjustable on the axle so that the separation between the driving wheels can be varied. The pawls engage the internally-toothed member 4 under the influence of gravity, but alternatively they can be urged into engagement therewith by springs; the pawls are so arranged that only one pawl can engage with the teeth at a time, the other pawls being disposed circumferentially in such a manner that their ends are then displaced relatively to the teeth by a distance equal to a fraction of a tooth, whereby the backlash of the freewheel is reduced. To reverse the direction of rotation in which the freewheel transmits drive, it is dismantled and then reassembled with the pawls in the position 7a ; such reversal of the pawl position also ensures that an unworn portion of the pawl is used in the new position, so that by interchanging the two wheels after reversing the pawls, the lives of the pawls are doubled.
